Laserradar and sonar based world modeling and motion control for fast obstacle avoidance of the autonomous mobile robot MOBOT-IV

Abstract

The obstacle avoidance mechanism of MOBOT-IV, which serves as a test platform within the scope of a research project on autonomous mobile robots for indoor applications is described. The mechanism utilizes heterogeneous information obtained from a laser radar and a sonar sensor system in order to achieve a reliable and complete world model for real-time collision avoidance. This world model is transformed by a motion control component into a virtual position deviation to perform obstacle avoidance by using a track-control algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
